' the casing as shown, in which space any suit- `Vpresents anupwardly-extending "cylindrical portion r45, thel vertical open-ing inwhich is of the same size in crosssection asthel channel portion 4v43and in direct vertical alinement therewith,fthe parts just referred toform-ing the cylinder portion of a pump hereinafter more fully.described and whichoperates to force the inolteirmetal out yof theVCrucible to the die inwhich the. strip yis to be formed, the cylinder45 containing passages 46. in its side wallthrough which the moltenmetal in the Crucible enters this pump The member `44 is providedwith alateral extension` 47 having at its' outer end an upright cylinderportion 48, there being a pas- -sage 49 communicating at one end withthe 'portion 43 ofthe channel 42. and opening through'tlie side wallofthe cylinder 48, this passage being controlledby valvemechanisinhereinafter described.

VThe mechanism125 also comprises a. cover vportion 50y for the Crucible,preferably formed with a heat-insulating section ,as represented at 51,this `cover containing an opening controlled by a hinged closure 52 andthrough which opening the condition of the metal within the Crucible maybe observed and through which opening the'metal may be charged intothecrucible.

The die to which the molten metal passes from the crucibleand whichforms a portion ofthe mechanism 26 is represented at 53, this die being.of substantially rectangular shape in cross-section and containing adie-opening 54- therethrough which at its outlet portion is of the samewidth and height as the vstrips to be formed therein, the bottom wall ofthis openingbeingso shaped asto cause the upper edge of the strip formedtherein to be of thel desired shape, namely, either fiat, as for examplewhere the strip is to be used in the making of-leads and slugs, or ofa'1 shape to produce arrule printing surface, as in the The -.die` 53 isi lengthwise of, an opening 55 extending through a housing 56 securedinthe position zshown (Fig. 3).toregister at. thev inner end of theopening therethrough withthe outer end of the channel 42,7the die 53,the crosslocated' in, and extends l sectional dimensions of which areless than those of the opening 55, reaching short of the crucibleextension 41, whereby a chamber 57 is provided in the member 56 betweenthe die 53 and the crucible-extension 41.

rlhe o'uter face of the crucible-eXtension 41 contains anoutwardly-Haring recess 41a into which the channel 42 opens, and intowhich a circular tapered boss 56a on the housing eX- tends, to make atight joint, the housing being secured in place by screws 56b extendingtherethrough and screwing into the extension 41.

The mechanism also comprises heating means for maintaining the metal inthe Crucible 37 and in the throat-portion thereof and in the inletportion of the die 53, in molten condition, the means for this purposecomprising an electrical heating unit 58, in the f-orm of an annulus,immersed in the body 59 of the metal in the crucible and surrounding thecylinder 45; an electrical heating unit located at the bottom of theCrucible and extending lengthwise along the channel 42; a pair ofelectrical heating units 61 and 62 positioned at the throat-portion ofthe crucible at opposite `sides of the outlet end of the channel 42;pair of electrical heating units 63 and 64 located in the housing 56 atopposite sides of the opening 54 and between the forward extremity ofthe crucible extension 41 and the forward, or outlet, end of the die 53,the supplying of current to these several heating elements beingcontrolled in any desirable way, as for example as disclosed in my saidco-pending applica tion for patent.

As will be understood, the provision of the heating elements 58, 60, 61,and 62, is to ensure the maintenance Vof the metal in fluid condition upto a point where it is caused to become set in the die 53 by thesubjection of the metal to cooling means, as hereinafter described.

The bot-tom heating unit 60 of rectangular plate-like,` form is secured,Vin any suitable way, flatwise against the underside of thethreat-portion of the crucible and the flat underside of the housing 56;and the heating units 61 and 62 of the saine form as the unit 60 litflatwise against opposite sides of the throat-portion of the Crucibleand the adjacent sides of the housing 56, the units 61 and 62 being heldin place by clamp-screws 61a threaded in the casing 35 and bearingagainst plates 61b between `which and the units 61 and 62 insulatingmaterial 61C, such as asbestos, is interposed.

t may be here stated that the die 53 is sealed in the housing 56 bymetal `supplied from the crucible 37 and to this end the passage 49is'provided whereby molten metal from the Crucible flows through thispassage and thence through the channel 42 into the space around the die53, the heating elements to heat the housing 56 to such a temperaturethat the metal supplied thereto is maintained in molten condition andcompletely fills the space around the die 53, whereupon the elements 63and 64 are deenergized and the metal around the die 53 solidities,sealing the latter in place.

The passage 49 contains a rotary valve 65 of cylindrical form located,and rotatable, in the cylinder 48 and having a cross port 66 which, whenthe valve is in one position, forms a part of the passage 49 but whenrotated to a different position, closes this passage, the valve 65having an upwardly extending stem 67 by which it may be rotated.

It will be understood that the heating elements 63 and 64 also serve asmeans, when energized, to melt the sealing metal around the die 53 topermit of the removal of the latter when desired.

In the forming of the strip, the metal supplied to the die53 is causedto solidify adj acent the outlet end of the die passage 54, and as ameans for effecting this result, the housing 56 is provided with achannel 68 which surrounds the die 53 and through which cooling water iscirculated, the arrangement shown for thus circulating water comprisinga pipe 69 which leads from any suitable source of supply of coolingwaterand opens into the bottom of the channel 68, this channelcommunicating at its upper end with an outlet pipe 70 discharging into adrain 71. The cooling water entering the bottom of the channel 68divides and flows upwardly through opposite sides of the channel 68 anddischarges through the outlet 70.

It is desired that during the energizing of the sealing units 63 and 64,flow of cooling water to channel 68 be discontinued and this channeldrained, the latter being effected through a pipe 70a valved at 7Gb andleading from the bottom of channel V68 into the drain 71.

As hereinbefore stated, the feeding of the molded strip, represented at72, out of the die 53 is` effected by pulling force applied theretobeyond the die `53, this feed being intermittent. formed of a continuouslength, the molten metal must be caused to iow into the dicchannel inthe die 53 in sufcient volume to maintain the same completely filled atall times. shown by the pump hereinbefore referred to and provided inthe Crucible 37, this pump comprising the cylinder 45 and a piston 73reciprocable therein and pivotally connected at 74 with the lower end ofa link, the upper end of which is pivotally connected at 75 with one endof a rock arm 76 journalled at 77 on a bracket arm 78 on the cover 50,the other end of the arm 76 beingpivotally connected at 79 with theupper end of a rod 80, the lower;`

The roller 83 is normally heldat all times against the periphery ofthe cam 84 by a coil spring 86surrounding the rod 80`and con- Ilined between a stationarymember 87 onthe frame of the machine and through an opening in which the rod 86 isreciprocable, and

stop means 88 carriedon the upper end of the rod 80, the piston 73 :thusbeing operated on its power stroke by the spring 86. v

rlhe parts of the machine are so proportioned and arranged, ashereinafter described, that during the movementl of the strip-feedingmechanism toward the die 53 for positioning this mechanism preliminaryto the ir'feeding of the strip lfrom the die, the piston 73 risesuncovering the openings 46 and per- 1 mitting molten metal to flowinto'the cylinder and during the feeding of the strip by thestrip-feeding mechanism the piston 73 isVV forced downwardly to forcethe molten metal through the channel 42 and into the dic-channel 54. v.

- j Referring now to therdetails of the illusjtrated strip-feedingmechanism 28, this mechanism comprises a base 108, in the form ofahousing ystationarily mounted on the bed 32 and containing in its upperportion a doveytail slot 109 extending longitudinally there-Y of.Mounted on the topof the member 108 isa slide 110 havingra dependingdovetail portion 111 interfitting with the walls of the dovetail'slot109, this slide being reciprocable on the member 108 lengthwise ofthemachine and parallel with the longitudinalaxisof the latter.

contains a-recess 112, the form of this recess belng such, as shown,thatone.of its side The'upper'v'surface of the slide 110 walls,representedat 113, extends parallel with the longitudinal axis of themachine and its opposite sidewall, represented at 114,

inclines toward the right-handv'end 0fy the ma'- chine in Fig. 5.awayfrom this axis. The wall 113 is lined with a bar 115 of uniform widthfaced by a filler bar 116 likewise-of l uinfuorm width, and the wall 114is faced by a-bar 117 of'1 uniform width with its inner yfupperedgeportion beveled as representedat 118. The kslide 110 is thusiformeol inits v Y upper surface with an effective recess defined by the opposingsurfaces of themembers 117 and 116, one side of which is parallel withthe j longitudinal axis yofthe machine V`and .sub-

stantially coincident with thev adjacentface of the formed strip 72, asshown in Figs. 5 and 6, and the other side of which is spaced from thestrip-72 and ilflclines toward the rising from, and secured to, theslide 110, the shaft 121 extending parallel with-the inclined inner faceof the member 117 The plate member 119isthus adapted to be-swungV atYits hinge'connection with the slide 110 into and out of the positionand' 6. 'A j Y In order that the strip-feeding mechanism,

shown in Figs. 5

thefurther `details of which are hereinafter described, may be adaptedfor thefeeding of formed strips of dierent, widths, the plate Amember119 is slidable at its extension 120 along the angularly disposed shaft121', the plate 119 being held in any desired position of adjustmentalong this shaft by gage-blocksV 123 pivotally mounted on a'rod 124secured at its ends inthe supporting blocks'122 and extendingfpa'rallelwith the y'shaft 121,` these 123a'at whichthey are yadapted to extendbetweenfthe vextension 120 of the plate 119 and the vadjacent supportingblocks 122. The gage-blocks are independently rotatable into and out yofthe position just stated,the dotted lines shown inFig'. 8 representingthe position to which the `blocks may beturned and thusitheeplate 119lmay be adjusted to any desired position along the ,shaft`121 and thegage-blocks then turned back to aposltion for holding the plate 119 infthe adjusted position. The gage blocks 123'are of graduated widths asshown and vbear legendsindicating the positions to which the plate 119should be adjusted along the shaft 12,1 tocorrespond with differentwidths of strip 72 to be operated on. Thus, inthe dr" '1wings,fthe plate119 is adjusted to a position for feeding twelve pica strips. If, bywayof example, eighteen pica stripsare to be fed, they gage blocksn123with the indication 187 thereon should be turned back, the plate-119adjusted to the right in Fig. 5f and this vparticular gage'block-positioned between the extension 120 and the one ofthe gage blocks123 desiglnated 12, it being noted that by adjusting the platemember119'to the right in Fig. 5,

.it is bodily shifted in a direction away from the strip 72 'and whenadjusted to the left in this figure, is bodilyl moved in a directiontoward this strip. .n l

The plate 119 is held against upward displacement from thel positionshown in Figs.

s 5 and 6, by a 'lock-bolt 126 vertically movable in an opening 126a inthe plate 119, its upper threaded end being engaged by a nut 1261. Thelower headed end 127. of the lock-bolt extends into a slot 128 in theslide 11() of Vblocksv being provided with lingerportions T-shape incross section (Fig. 6), this slot being enlarged at one end, asindicated at 129, which permits the plate 119 to be swung on its hingewhen this plate is moved along the shaft 121 to a position in which thehead 127 of the bolt 126 registers with the enlargement 129.

The slide 110, together with the parts carried thereby, is reciprocatedby means of a pin 130 depending from the slide and provided with aroller 131 which extends into the continuous cam groove 132 of a cam 133mounted on the upper end of a shaft 134 j ournaled in a bearing 135 onthe base plate 32, this shaft being driven by a bevel pinion 136 meshingwith a bevel pinion 137 on the shaft 85.

Located in a recess 138 in the member 119 and extending into the recess112 in the body portion of the slide 110 is a wedge block 139 betweenthe side 140 of which and the liner strip 116, the strip 72 extends(Figs. 6 and 7), the opposite side of the block 139 being inclined, asrepresented at 140, at which portion it is provided with a series ofball-bearings 141 held in spaced relation to each other by a cage 142,these balls opposing the inclined inner face of the liner strip 117 asshown in Fig. 6. f

The wedge block 139 is loosely engaged by a crank pin 143 on a shaft 144extending crosswise of, and journaled in, the member 119, the shaft 144having a radially-extending pin 145 connected with one end of a coilspring 146, the opposite end of which is connected with a pin 147stationary on the member 119, the arrangement of these parts being suchthat the spring tends to rotate the shaft 144 in a direction to forcethe wedge-block 139 to the left in Fig. 5, namely, into wedging positionagainst the strip 7 2. The 'outer end of the shaft 144 has `rigidthereon a cylindrical head 148 containing a recess 149 in` the lowerportion of its periphery in which a roller 150 is journaled to partlyproject beyond the periphery of the head 148, this roller, in theposition of the parts shown in Fig. 5 being shown as substantiallyvertically alined with the axis of the shaft 144.

On the stationary member 108, directly below the path of movement of thehead 148, is aI bar 151 adjustable longitudinally of the machine in agroove 152 in the upper side of the member 108, this bar being adjustedby means comprising a shaft 153 journaled at 154 on the member 108 andheld against lengthwise movement and having threaded engagement at itsinner end with the adjacent end of the bar 151.` A clamp screw 151ascrewing at its end into the bar .151 and extending into a slot 151b inthe member 108 affords means for maintaining the bar 151 againstaccidental displacement.

The bar 151 is provided on its upper surface, at one end, with a raisedportion 155 having an incline 156, the prtion155 being at such anelevation that in the movement of the slide 110 to the left in Fig. 5,the roller 150 engages the incline 156 and rides upon the portion 155with the result of rotating the shaft 144 in a direction to shift thewedgeblock 140 toward theright in Fig. 5, thereby overcoming thetendency of the spring to force the wedge-block into wedging engagementwith the strip 72. The parts just described remain in the relativepositions stated until the roller 150, in the movement of the slide 119to the right in Fig. 5, moves beyond the raised portion 155, whereuponthe spring 146 becomes effective to exert yielding pressure on the wedgeblock 140 tending to shift it to the left lin Fig. which results in thefirm gripping of the strip 72 between the wedge-block and the linerstrip 116 for effecting the feeding of the strip 7 2.

lt will be understood by adjusting the bar 151 lengthwise of themachine, the length of the feed stroke may be increased or diminishedrasdesired, this being of advantage in that, in general, the thicker themolded strip to be formed, the shorter the feed stroke should be.

Located to the right in Fig. 5 of the feed mechanism 28 is apresser-device 157 in the form of a lever 157"- fulcrumed at one end, asrepresented at 158, to a stationary part of the machine and equipped atits other end with a roller 159 held down against the upper edge of thestrip 72 by a screw 160 freely rotatable in the lever 157a and screwingat its lower end into the stationary part to which the lever 157a ispivoted, a `compression spring 160'1 holding the lever 157a against theunderside of the head of the screw.

The mechanism 29 for clamping the molded strip 72 against retrogrademovement in the movement of the slide 110 to the left in Fig. 5comprises a cylinder 161 mounted on, and rigidly secured to, a bracket162 secured to the bed plate 32, this cylinder containing a piston 163slotted between its ends at. 164 and containing a cross pin 165 which isstraddled by the upper forked end 166 of a lever 167 which extendsupwardly into the slot 164 and is fulcrumed at 168 on a stationary partof the machine. The piston 163 is backed by a coil spring 169located inthe end of the cylinder 161 and interposed between the piston 163 and anadjustable stop-plug 170 screwed into this end of the cylinder. TheoppositeV end of the piston 163 contains a horizontally `extending slot171 into which a horizontally extending clamp bar 172 extends freely,this bar being located alongside of the molded strip 72 and operatingwhen the piston 163 is moved to the right in Fig. 9 to clamp the strip72 against a stationary bar 173 secured to an upstanding flange 174 onan extension 175 of the cylinder 161.

The clamp bar 172 at the portion thereof to bears continuously.

theleftin Fig. 5 of the cylinder 161, is connected" with` aspring-pressed plunger 176 mounted in a socket 177 in an extension v17 8of the cylinder 161 which operates not only to f -preventlengthwiseshifting of the bar 172,

but also causes 4the left-hand end of this bar in'Fig. 5 to pressrelatively lightly against a side of the Vmolded strip 72.V vTheconnection between the.A plunger 176 and the bar 172 i 'comprises a pin-179passing through 'the bal- 172 and through the outer yend 180 of theplunger' 176 which is set into a recess 181 in theside of the bar 172.VThe spring for .presse ing the plungertoward the bar is representedVfat182. yIt surrounds a stem 183 of the plunger andis confined betweenVthe. plunger and the end wall of the recess 177. The stem 183 projectsoutwardly beyond the cylinder extension 178 where it is pivotallyconnected lat 184 to amanually'operated lever 185 fulend, as indicatedyat '186,

crumed at its lower to the extension 17 8.` Y

vThe mechanism for operating the piston 163 to clamp the formed strip 72during the movement of the'slide 110 to the left in Fig. 5 comprises thelever167 above referred to, the lower end of which'isprovided with aroller 187 and a cam188 rigidly'secured to the main shaftA 85 andagainst which the roller 187 Referring now tothe mechanism 30 forsevering'the formed strip 72 into strip-sections of the ydesired length,this mechanism comprises a knife 189-reciprocably mounted inay recess190 having a cover-'plate 191, in a block 192 rigidly connected by a pin193 with a rod 194 between the ends of the latter. The rod 194isreciprocable in alined openings 195 and 196l in spaced-'apart uprights197 and 198'on a stationary'bracket member 199 se-l curedto the bedy 32of the machine. -The block 192 contains an openingv 200 therethrough atwhich it is slidable on a stationary tracted position shown in Fig. 12.

moved to the left in Fig. 15.

The rod 214 is equipped Y witha device.y

which extends into the path of movement of the terminal end of theformedV strip 72 and which is moved to the left in Fig.115,together`Vwith the rod 214, in the continuin-gmo'vement of the formed" stripv 72,the .device ref .ferred to being adjustable into dierent positionslengthwise of the rod 214 to provide andv interposed vbefor the cuttingof the formed strip into stripsections ofany desired length.` Y

The device just referred-tocom'prisesa block y224 loosely surrounding,and movable along, the rod 214 and containing a recess 225 into Vwhich atappet-vbar 226 extends between its ends, this bar being securedto theblock 224 by screws 227, the bar226Y extending lengthwise of',and'parallel'with,the rod214.

The'bar 226 is provided at opposite ends with lugs 228 and 229 andadjacentthe'lug 229 with a cross pin'230 which extends into verticallyalined recesses 231 in the upper and lower walls of the recess 225, thisThe lbar226 is provided for 'engagement by the terminal end of theformed stripr72 and is reversible end for end in the Yblock 224 topresent either lug 228 or 229l to thestrip 72, Vdepending on the lengthof the tions to be provided, the bar 226l being posi# tioned reverselytothe positionv shown in the pin servingVVV to properly position the bar226 inthev block drawings when it is desired to produce very VThe block2,24 is-Y associated with ali-'sleeve Ymember 232 surrounding, andslidable along,

- which the block 224 may be moved lengthwiserelative to the sleevemember 232, this block and sleeve being held against relative rotarymovement by a pin'236 on the head 233 which slidingly extends into arecess 237 in the block 224. To prevent accidental rotation of the nut235, a shoe 238 slidable in a recess 239 in the block 224 and pressedagainst a face of the nut 235 by a spring 240, is provided.

The rod 214 is provided along a side thereof with a seriesof notches 241with which a pawl 242 on the head 233 of sleeve member 232 engages forlocking this sleeve member in `adjusted position along the rod 214. Thepawl 242 is slidably mounted in a socket 243 in the head 233 and isbacked by a spring 244 which urges the pawl toward the notched side ofthe rod 214. Slidable in the outer end of the socket 243 is a plunger245 which, at an opening 246 therein, freely surrounds the rod 214 andopposes the pawl 242 and by which the latter may be pressed, against theaction ofthe spring 244, out of engagement with the notched portion ofthe rod 214 to .I permit the sleeve member 232, together with has a flatsurface 249 extending closely adjacent the iiat surface 247 of the rod214.

It will be understood from the foregoing that in the feeding of theformed strip 72 to the right in Fig. and to the left in Fig. 15, l

the terminal end thereof engages the end of the tappet-bar 226 opposingit, thereby shifting this bar and with it the rod 214 and, through thespring connection 222, the block 192 and rod 194, which causes the knife189 to extend into the path of movement of the lever 207 in the rockingof the latter which occurs only when the strip 7 2'is at rest, the stripthus being severed into a strip section ofa length gaged by the settingofthe tappet-bar 226 along the rod 214 by the mechanism' abovedescribed.

The return of the cutter-equipped block 192 to the normal position shownin Fig. 15 is provided for primarily by a direct mechanical connectionwith a positively driven part of the machine, as for example andpreferably the slide 110, though the spring 220, through the abutment ofthe rod 214 with the rod 194 exerts force, urging the block 192 to thenormal position stated.

The mechanical connection shown comprises a bracket 250 connected with,and rising from, the slide 110 and containing an opening 251 in whichthe shank 252 of a screw-device 253 is slidably movable, a coil spring254, surrounding the shank 252 and confined between flange 255 on theupright and a disk 256 on the shank, yieldingly holding the device 253at a shoulder 257 thereon against the upright 250. The other end of thescrew-device 253 is screwed into a tube 258, containing a slot 259extending longitudinally thereof, and telescoping with the ad jacent endof the rod 194, the latter having a projection 260 at its side whichslidingly eX- tends into the slot 259.y

1n the normal position of the mechanism shown in Fig. 15, namely, theposition in which the cutter device 189 extends out of the path ofmovement of the lever 207, the slide 110 may reciprocate withoutaffecting the position of the cutter-equipped block 192,

9 but the arrangement of the various parts described is such that themovement of the slide 110 to the left in Fig. 5 following the shiftingof the block 192 and the rod 194 to the left in Fig. and the concludingof the strip cutting operation, causes the lefthand end wall of the slot259 (viewing the slot in Figs. 15, 16 and 17) to engage the projection260 on the rod 194, in the final movement of the slide to the left inFig. 5, thereby positively ensuring the returning of the block 192 tonormal position (Fig. 15) in which the cutter 189 is out of the path ofmovement of the actuating lever 207. The spring connection between thescrew-device 253 and the upright 250 is provided primarily asshock-absorbing, or cushioning, means, the spring connection 222operating to prevent damage to the operating mechanism in case anyobstruction to the movement of the block 192 to normal position ispresented.

To the' right in Fig. 5 beyond the cutter 189 is a guide bar 261 for themold strip 72, this bar being of angle shape in cross section andiitting over the upper corner ledge 262 of a table portion 263 securedto the brackets 199 and 34. The inner edge 264 of the upper iiange 265of the bar 261 flatwise opposes the molded strip 72 and its dependingflange 266 carries spaced-apart adjusting screws 267 (one only of whichis shown) which are rotatable in the flange 266 and are held againstlengthwise movement therein, these screws bearing at their inner endsagainst the adjacent edge of the table top vif 262. By adjusting thesescrews the bar 261 may be .adjusted for formed strips of differ* entwidths, the table top being shown aspro* vided with markings to guidethe operator in adjusting this bar. .y The left-hand end, in Fig. 5, ofthe bar 261, ispreferably provided with a finger 268 Ihaving La recedingsurface 269 which ensures the proper guiding of the end of the formedstrip 72 yinto a position in which it movesalongthev side 264 of Vthisbar.

l severance of the strip 7 2, the block 192 is pro-V vided Vwiththeplate 213 presenting a knife v 4In' order that the cutter 189effect'clean edge 212 which backs the formed' strip at the l'-line ofseverance.v

The molded strip 72 should press firmly against the stationary cutterplate 213 at the beginning of the cutting operation and to ensure thiscondition a presser-plate 270 is provided opposite the stationary cutterplate 213, the platey 270, Vwhich has an outwardly deflectedstrip-guiding end-portion 271, be-

ing connected with one end of a pin 272 slidable'in the block 192, thispin being pivotally connected at its outer end with theV lower endVV ofalever 273 fulcrumed at 274 on the block 192'and having .a screwfpin27 5threaded at its upper end, thescrew27 5 `bearing against apart of theblock and, holding the plate 27 0l against the side of the formed strip7 2 with the desired pressure.

.As will be understood,ithe-cutter 189, inV

v performing4 the cuttingV operation, shifts the :severed end of thestrip-section to the left in l Fig. 13`beyond the path lof movement ofthe strip 72, from whichthe strip-section was cut, and as a means forholding the stripsection in the displaced .position referred to )andthusout of Ythe path of movement ofV the terminal end'ofthe continuousstrip 72 Y.

as it is fed through the machine, a dog 276 which locks the strip outofsuch'path, is pro- 5.0 fin front of the severedstrip-section and holdsvided. This dog is in the -form of Ya lever :pivoted'at 277 .to theblock 192and bearing .Y by gravity upon the top of the strip 72 vas thelatter is advanced beneathit by the operation of the machine.' When ythecutter shifts the strip section, as stated, this dog drops'down it outof the rpath `of movement of the advancing strip which latter, at itsupper sur- .Y

. s face, engages the dog and lifts it so that when the next stripsection is cut,fthis dog drops in frontof this section, the movementsjust de- `:scribed continuing throughout the continued operation ofthemachine; A f

.The strip-section-stacking mechanism 31 comprises the table top 263upon the top Vof `which a follower device 278 is'mounted toY extendparallel with the path of movementof v'the continuous formed strip 724through the machine. The follower 278 is connectedat 279 with the upperreaches of sprocket chains 280 '281 which engage `sprockets v282 and 283carried by-Ystub shafts 284 and 285 jour-y naled on the table top, whichlatter is slotted to receive the upper .reaches of the chains, asrepresented at one portion thereof at 286. The chains also engage Vsprockets 287 and 288, respectively, rigidly secured to a shaft 289journaled on a stationary part ofthe machine below the table top. j j YK i The follower 278 `is yieldingly urged toward the molded strip 7 2bya `coiljspring290 encircling theshaftj289, the end 291 of this y coil-spring being secured to a stationary part of the machine and its otherend Voperativelyk connected withthe shaft v289 and serving to rotatethis'shaft in clockwise direction in F ig.

14. To provide for the' adjustmentof the I as shown inFg. 5, thefollower278receding in opposition to the action of thevspring 290 as thestack of sections increased.V

t The particular illustrated construction of follower `278 comprises amain body portion 296 of angle shape in vcross section at which thefollower is attached to the chains 280 and Y 281. Extending along theupwardlyeextending Hangs-portion 297 of the part 296, and adjustabletherealong, is astripV 298 having rearwardly-extending l headed lstuds299 which project at their Yreduced Vportions through elongated slots300 inthe flange 297, thus permitting ofthe shiftingof the strip 298lengthwiseV of the machine, whereby the follower may be conditionedforvoperating in the'most desirable way for 'the stacking ofstrip-sections ofgreatly varyinglengths, For the shorter lengths ofstrip-sections, the strip 298 'is preferably adjusted to the-'positionshownin Fig. 14. For the longer stripsections, it 'ispreferablyshiftedfto the right .in thi-s figure. j A coil spring 301 carried by`the body portion 296 andi extending through a slot 302 intheflange 297and engaging at its free end Vwith the -strip 298, tendstoyield` inglyhold the latter in the position shown` in the drawings. The shifting ofthe strip 298 to the right inthis figure is against the ten-` sion ofthespring 301, the strip being held in such shifted position'byswinging adog- 303 pivoted lat 304 on the flange 298, into a posi'-V tion toengageand fora stop for, the adjacent stud 299. Y, As will be understoodfromjthe foregoing CII description, the drive for all/ofthe positivelydrivenV parts ofthemachinesis through the drive shaft 85, this Shaftbeing shown as driven by an` electric motor 305 shown as mounted on theframe of the machine and driving a belt 306 engaging a pulley 307 rigidwith a pinion 308 meshing with a gear 309 keyed to the drive shaft 85.
